The study, which reviewed more than a million patient encounters between 2000 and 2012, showed a significant year-on-year reduction in the management rate of genital warts in women aged 15-27 years since the vaccination program started. The findings are published in PLOS Onejournal.

“The results show that the program has been a widespread success,” said lead author of the study Christopher Harrison of the University ofSydney.

The HPV vaccination program was introduced in 2007, and the rate of genital wart presentation fell dramatically from 4.33 per 1,000 encounters pre-program (2002-2006) to 1.67 per 1,000 encounters in the post-program period(2008-2012).
